Ultranationalism or extreme nationalism is an extreme form of nationalism in which a country asserts or maintains detrimental hegemony, supremacy, or other forms of control over other nations to pursue its specific interests. Ultranationalist entities have been associated with the engagement of political violence even during peacetime. The belief system has also been cited as the inspiration for acts of organized mass murder in the context of international conflicts, with the Cambodian genocide being cited as an example.
